CVE-2026-107700
CRITICAL 9.3dot-access 0.0.3 through 1.0.0 contains a code injection vulnerability that allows remote attackers to execute JavaScript by supplying crafted paths to get(). The path is concatenated into a new Function body in index.js, so attackers can reach constructor.constructor to load child_process and run operating system commands in the Node.js process.
Severe if exploited (CVSS 9.3), but no known exploitation and low modeled probability. Patch on a normal cadence.
